Shingles is primarily caused by the varicella-zoster virus, which enters the human bloodstream through the respiratory tract mucosa, leading to chickenpox or a latent infection. The virus then lies dormant in the nerve ganglia of the body. Certain triggers, such as trauma, fatigue, weakness after illness, malignant tumors, or the use of immunosuppressants, can decrease the body's resistance and activate the dormant virus, resulting in shingles.

Does shingles itch?

Shingles most often leads to the formation of long blisters or herpes, accompanied by significant pain, which is the experience of most patients. However, a minority of people may not feel significant pain but instead experience itching. This is also a manifestation of the inflammation caused by shingles. Therefore, some patients with shingles feel itchy. Both itching and pain require timely antiviral treatment, along with medication that nourishes the nerves.

Does shingles recur?

Shingles, this skin disease is recurrent. Not only is it contagious, but it also has a propensity to recur. The likelihood of recurrence is greatly influenced by one's own resistance and also greatly related to the people one comes into contact with. Therefore, after recovering from shingles, it is essential to avoid further contact with other shingles patients or those with chickenpox. One should balance work and rest, drink plenty of water, get adequate rest, and enhance personal immunity. If shingles recurs, it is crucial to seek timely treatment at a reputable hospital.

Does shingles require isolation?

After developing herpes zoster, isolation is generally not necessary. This disease is mainly caused by a viral infection of the skin and often related to the patient's low immune resistance. It has very low infectivity, and it is generally unlikely for people with normal immune resistance to be infected. Therefore, isolation is not needed after contracting herpes zoster.

What is shingles?

Herpes zoster is a viral skin disease, and humans are the only hosts for the varicella-zoster virus. Therefore, the virus can easily enter the bloodstream through the respiratory tract mucosa, leading to viremia, and consequently causing chickenpox or presenting as a latent infection. The virus can lie dormant for long periods in our ganglia or nerve roots. When the body is stimulated again, leading to a decrease in resistance, the dormant virus can be activated, which may result in herpes zoster.

How long does it take for shingles to heal?

The symptoms of shingles can generally be divided into two categories. The first involves blisters on the skin, typically unilateral, and the second is that these blisters are often accompanied by pain, which varies in intensity from person to person. Generally speaking, the older the individual, the more severe the pain may be. As for the duration until recovery from shingles, the skin symptoms usually heal within two to three weeks for young people, but for older adults, it generally takes about three to four weeks. If the rash leads to a secondary infection, the recovery may take even longer. This is the duration for the alleviation of skin symptoms. If the condition involves nerve pain, the recovery might take longer. For people over 50, the duration of nerve pain can be significantly longer, and some may experience postherpetic neuralgia, where the skin symptoms have disappeared, but the nerve pain persists, possibly lasting for months or even years.
